Specification forming part of Letters Patent N o. 188,355, dated March 13,1877; application filed January 31, 1877.

To all whom t may concern:

Be it known that I, LOUIS GODDU, of Winchester, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Fastenings v for the Soles of Boots and Shoes, of which the following is a specification:

My present improvement relates to solefastenings for boots and shoes, formed in continuous lengths of integral wire or -rods of nailsor pegs having heads and points, and adapted to be fed by the inserting-machine and severed into nails or pegs, such severance being either made before or after the nail has been inserted, the heads ofthe integral nails or pegs serving as the means for making and governing the feed and determining the point at which each nail is separated from the continuous wire.

The invention herein consists of a wire or rod of nails or pegs having heads only upon one side, the other side being plain and preferably hat-that is, an uninterrupted surface, the design being to obtain a more certain feed of the wire and prevent it from turning within its passage or feed way by interrupting the cylindrical form of the head and giving it, in cross-section, a attened or semi-oval shape.

I nd that this form and make give greater holding power to the continuous wire or rod (particularly when IWire of small diameter is used) than if'the heads and points were made with coincident indentations, besides allowing the wire or rod of headed nails to be more readily coiled for use in the machine, and prevent accidental breaking.

Another important point is, that I provide the face of the corrugated side of each peg or nail in the continuous length with a line rib extending from the head to near the point, and in the middle ofits Width, to form a bearing or ridgeway for the feed device to slide against until it strikes the head,and thereby insure the feed-dog to always strike and act upon the head of each nail to make the proper feed, yet guard it from contact with the corrugated surface. The intention is to employ a feed device which may also serve as the severing-point, and to make such severance before the insertion, and at a point which leaves the nail in posit-ion to be driven by thev kdriving mechanism.

In the accompanying drawings, Figure l represents a view of a piece of the continuous wire of nails or pegs illustrating my invention; Fig. 2, an edge view; Fig. 3, a view of y the headed and beaded side of the same; and Fig. 4, a view of one of the severed nails driven into the sole and clinched.

The wire or rod in continuous length is rolled or formed with a flattened or oval side, corrugated or smooth, and enlargements a, at suitable intervals, to form heads for each distinct nail or peg upon the opposite side, the

spaces between the heads and points on this side being also iiattened and tapered to form the point b to each nail. The heads and points are thus joined, and the Wire may be `of suitable size and length. `By this construe tion the nails or pegs may be said to be formed upon one side of the wire only, which gives the advantage of greater strength and durability in handling, while admitting it to be more readily and compactly coiled.

The essential object, however, of this construction is to obtain a more certain feed of the wire from the coil into the machine by reason of having the iiattened and plain side free from interval enlargements, and thus give the Wire an oval and oblong form in crosssection, which prevents it from turning inv its passage or feed way, thereby always insuring the proper action of the feed device upon the head. There can be no slipping,

and hence no 4interruption of the feed, thefeedway being, ofcourse, suitably adapted for such a peg-Wire.

The headed side of the wire has, if desired, transverse corrugations, which extend Ifrom the head to nearthe point of each nail, to give it a more secure hold when driven. This side of each nail may be of any desired form, and may taper to the point.

As the feed of the wire is made by the action of the feed device over and upon the heads, it might catch upon or into the corruy gations, and thus give an irregular or too great feed; so I avoid such a contingency by forming upon the corrugated surface and in the middle of its width a fine rib, i, running from thehead tonear theupoint,` upon vvhichg` the feed device has its bearing, and by which it is guarded from contact with the corrugathe rib can be dispensed with.

-The forming .of the heads `or shoulders ofi each nail upon one side of the coutinuouswire gives greater strength at thejunction thereof withpthe point, and the Wire can be coiledv up-` on `its flat side and unwoundfwithout being? easily brokenV at itsweakest points.

Bothsides ofthe wire upon the nai1-shanks may be roughened, ifdesired, `and the new manufacture readily and cheaply made and` furnished for the trade in coils of suitable size. The rib z' may he formed on both sides ot' the nail-shank, ifl desired. l

I claim- 1. As `a `new manufacture, a continuous lengthof Wire or rod of nails or pegs adapted for ready separation, `having surface enlarge ments upon one sidefonly,`to form the heads` of the nails, substantially as and for the purpose herein set forth.

2. Acontinuouswire of nails or'pegsyihving` surface `enlargements lto `form nheads on one side only, and aflat or oval surface corrugated or smooth on the opposite side ofthe nail-Wire, for the purpose stated.

3. A `continuous length Aof wire or rod, adapted `for ready `separation `into nails or pegs, having heads and `points formed upon its corrugated side, an uninterrupted fiat or oval snrfaceon theloppositeside, audlane rib uponthe corrugated shank-surface, for the purpose herein set forth.

4. A `continuous lengthof `vvirmortrod.'` of nails or pegs, having aline rib, i, on the shanksurface of each nail, as herein set forth.

, In testimony whereof I have hereunto set my hand in the presence of two Witnesses.`
